OK Gene, here you go and I only have 60 posts.
Here is what I would charge in Philly....
Drive into Center City $250

Add for traffic delays $115
To pay the guy to watch my truck and tools all day $20 (or 3 40 oz Malt liquors, whichever is cheaper. Remember, don't give them to him until end of day)

Meter money x 15% $21.50
Hazardous work pay $450

Actual labor (standard install) $600
Cover lost scrap revenue when someone steals old storm door $75
2 hr extra labor for time spent dodging ________ (dogs, drug dealers, bullets) $150
Am I forgetting anything? I don't think we need any permits so you can save the HO that and forget about the city wage tax, you won't be there long enough.
So that brings us to a total of $1681.50. Good price for this area
